A Kid & Dog-Related Rant

Ok, none of us here are generally prone to rants, but this was just too much. Yesterday we had a strange young man come to our backyard fence and begin smacking it with a stick, teasing and barking at our youngest Boxer, Francis. When she went towards the fence, he starting poking the stick through it, trying to hit her. The weirdest part (besides the fact that he was bold enough to come into the yard like that), was that we were sitting right there on the patio! I told him to knock it off and go home, and his reply was basically something you can't repeat on family-oriented websites. He did leave though (after telling us he'll mess with our dogs any time he pleases), so I just chalked it up to poor parenting and kid stupidity.
Then he came back today.
I put Francis in the house as soon as he started his routine, so he then chose to ride his bike back and forth on the road yelling cuss words and "where's your dog, lady?"
I don't know what the kid's malfunction is, but this is a really quiet neighborhood where anything unusual attracts a lot of attention, so the next door neighbor called the sheriff out. He took the kid (who turned out to be 14 years old!) home in handcuffs, and told us that if he came back they would arrest him for tresspassing, harrassment, and a few other things if we would press charges. You bet your britches I will!
I'm truly boggled at why a kid of that age would think such a thing was amusing, and even further boggled by what sort of parents raised a kid to act so rotten!
And folks say that *Dogs* should be on leashes? Hmmm..
